[android-developers] Re: How to calculate distance between to city (dynamically)
Android has a distanceTo method that does this for you, it's in the Location class (see http://developer.android.com/reference/android/location/Location.html#distanceTo%28android.location.Location%29) So, for instance: Location amsCentral = new Location(Amsterdam CS); amsCentral.setLatitude(52.3791); amsCentral.setLongitude(4.9002); Location histMuseum = new Location(Historical Museum); histMuseum.setLatitude(52.370247); histMuseum.setLongitude(4.889731); float distanceInMeters = histMuseum.distanceTo(amsCentral); (P.S. The distance between the above two locations is 1216.0496 meters ;-) On Sep 17, 7:42 am, Maps.Huge.Info (Maps API Guru) cor...@gmail.com wrote: The Haversine formula computes distance between two points along a spheroid (such as Earth).

Doesn't the method of Location class implement the same formula???

you can also use 'haversine' formula. google it. you need two geopoint. On Sep 16, 3:36 pm, Rocky rkjhaw1...@gmail.com wrote: Hi Shashidhar, Thanks dear...

The Haversine formula computes distance between two points along a spheroid (such as Earth). You will need to know the coordinates of each city to use this formula. Coordinates for nearly all cities in the world can be downloaded from the geonames.org website for free. The Google geocoder will also return those coordinates but you'll have to obey the terms in order for you to use that service. For the exact formula, try searching Google. -John Coryat -- You received this message because you are subscribed to the Google Groups Android Developers group.
